Take for example this image:
For efficiency purposes I will have many images embedded into a single texture. I was going to make a reusable material that will allow for pulling a section from the texture with start/length parameters. I understand UE supports Paper2D with atlas groups but it seems as though it is for animations. Also, the material I need could be used for UI via/UMG or 3D gameplay. Is there an existing node in the material editor that allows one to pull segments out of a single texture or do I have to create it?
